3.1 Applicable Cable and Terminal Tightening Torque
The size of the terminal screws is M3.
The end disposal of the cable shows below.
Tighten the terminal to a torque of 0.5 to 0.8N m.
•
Do not tighten terminal screws with a torque outside the abovementioned range.
Failure to do so may cause equipment failures or malfunctions.

*2 The [FG] terminal and the [ ] terminal are connected internally.
There is no "FG" terminal for ch1. When using ch1, connect directly to the
[ ] terminal.
*3 Use a 2-core twisted shield wire for analog input line, and separate it from
other power lines or inductive lines.
*4 For the current input, short-circuit the [V+] terminal and the [I+] terminal.
*5 If there is voltage ripple in the input voltage or there is noise in the external
wiring, connect a capacitor of approximately 0.1 to 0.47µF 25 V.
3.4 Grounding
Grounding should be performed as stated below.
• The grounding resistance should be 100Ω or less.
• Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared
grounding" of the following figure.
